Best Slideshow Software

Reading the other threads, it is claimed that PicturesToExe is the only software that uses hardware rendering, and therefore maintains the input resolution. The others downsize for DVD.

My main concern is image quality, and from what I've seen PicturesToExe is superb -exactly what you see in Photoshop.

But, is this claim about hardware rendering true? And, leaving DVDs aside does any other software compare to the image quality PicturesToExe produces. I only ask because I find it very amateurish in terms of software usage, and have recently being using Premiere Pro where I had much more control, particularly of music volume and sync.
